INTRODUCTION 

Mathematical morphology is a powerful tool for geometrical shape analysis, description and extracting features from an image. Mathematical morphology uses the concept of mathematical set theory for extracting meaning from the image [7]. The main aim of this study is to transform the digital images into different forms. Image processing techniques are used with wide varieties of applications. The requirement is different for different applications. This study is mainly focused on how to transform the image using mathematical morphology so that it can be suitable for the respective applications. Mathematical morphology has been chosen to explain how images are used to illustrate mathematical set theoretic operations, such as union, intersection by means of morphological operations like median filtering, Dilation, Erosion and Binarization. There are numerous applications using different binary morphological operations e.g., object recognition, tracking, and region filling. The existing binary morphology employs the image processing with MATLAB simulation. Hence the synthesis could be done with FPGA architecture. Binary image processing is a powerful tool in many image and video applications. Hence a reconfigurable processor is presented for binary image processing in this method.. Reconfigurable computing represents an intermediate approach between the extremes of Application Specific Integrated Circuits (ASICs) and generalpurpose processors. A reconfigurable system generally has wider applicability than an ASIC [8]. Also, most generalpurpose processors would very likely not satisfy the performance constraints for the entire application.  
RELATED WORK 

A chip with a 500dpi cellularlogic processing array was implemented to enhance and verify fingerprint images [1]. A pointing device using a specialized algorithm was presented for motion detection in [9]. The MIPA4k, as presented in [2], was a 64×64 mixedmode array processor for identifying local binary patterns. All the abovementioned chips are designed for specific applications. The major drawback of applicationspecific chips is the lack of flexibility. The reconfigurable technique can bridge the gap between applicationspecific integrated circuits and flexibility. A programmable single instruction multiple data (SIMD) real time vision chip was presented to achieve highspeed target tracking [10]. In [11], a programmable binary morphology coprocessor was introduced to the visual content analysis engine of the chip used for visual surveillance. It has been a common practice to build applicationspecific chips for realtime binary image processing [1], [2]. However, such chips have a limited application range. On the other hand, the generalpurpose binary image processing chips mentioned above have their own problems. Some of these chips are made of analog circuit [3], [4], and some are made up of an analog part and a digital part [10], [5]. When compared with the digital part, the analog part shows low robustness, accuracy, and scalability although it has a small area and low power consumption [5]. Other generalpurpose chips have the architecture of a digital processor array, in which each digital processor handles one pixel. When large sized images are processed, the chips will become extremely large. Thus, further studies are needed to design a high performance, small size, and wide application range chip for realtime binary image processing.Reconfigurable systems are computing systems that combine a reconfigurable hardware processing unit with a softwareprogrammable processor.  
ARCHITECTURE 

The processor has the merit of high speed, simple structure, and wide application range. The architecture of the proposed processor is shown in Figure1. A binary image processor that consists of a reconfigurable binary processing module, including reconfigurable binary compute units and output control logic, input and output image control units. The performance of the processor is enhanced by using the dynamic reconfiguration approach. Basic mathematical morphology operations and complicated algorithms can easily be implemented on it. The processor has the merit of high speed, simple structure, and wide application range.  
The core of the processor is a reconfigurable binary processing module consisting of binary compute units and output control logic as shown in Figure.2. The processor also has Memory, the input and output control logic units, the process control unit. Reconfigurable binary processing module can be divided in to two main parts. First output control logic unit and the second part consists of several binary compute units. Each binary compute unit perform different operations such as median filtering, Dilation, Erosion and Binarization respectively.  
The Block diagram consists of two parts. The first part is the output control logic ,which selects the output from all the binary compute unit outputs according to the given parameters. The second part consists of several binary compute units that perform binary logic and binary image operations at high speed. The binary image algorithms are realized by the operations in the individual binary compute units and the connection pattern of these units. Each binary compute unit perform different operations such as median filtering, Dilation, Erosion and Binarization respectively .The operation executed in a binary compute unit is decided by configurable registers, including logic operation parameters, image resolution parameters, mask sizes, input and output selection parameters.  
BINARY COMPUTE UNITS 

Binary compute units perform binary logic and binary image operations at a high speed. The binary image algorithms are realized by the operations in the individual binary compute units and the connection pattern of these units. A. Binary compute unit1: Median Filtering using Sort Optimization.  
Median filtering is a nonlinear method used to remove noise such as salt and pepper noise from images[6]. The median filter works by moving through the image pixel by pixel, replacing each value with the median value of neighboring pixels.  
The formula of median filtering can be expressed as:  
First, we must sort the data by column. We need to do 9 comparisons to get the following result, we assume the result is  
A1>B1>C1  
A2>B2>C2  
A3>B3>C3  
Secondly, we need to find the maxim data in C1, C2 and C3 by doing 2 comparisons, and find the minimum data in A1, A2 and A3 by doing 2 comparisons, and find the median data in B1, B2 and B3 by doing 3 comparisons .The formula is as follows  
Amin = min(A1,A2,A3)  
Bmed = med(B1,B2,B3)  
Cmax = max(C1,C2,C3)  
Lastly, we need to find the median data in Amin, Bmed and Cmax by doing 3 comparisons.  
Fmed = med?Amin, Bmed, Cmax?  
The resulted Fmed is the final result. In the next circle, the comparison results of ?A2,B2,C2? and ?A3,B3,C3? have been obtained, we only need to seek the sorting of the updating data A4, B4, C4, and then use previous equations to calculate the required median. The processing element (PE) is the basic processing unit, which is designed for comparing 2 input data. D stands for D flipflop, whose function is to make a singlecircle delay. It is used for synchronizing the calculation here. Because the proposed algorithm needs to store two groups temporary data in current processing, we design two D flipflops to realize this function.  
The data in A,B and C will be sent to the ordering comparator for data ordering, and the results will be send to next different comparators as shown in figure 4. Before the second comparing, the data need 2 circle delay to distinguish the circle order of input data by two D flipflops. The second comparing results will be sent to the final median comparator to get the final result.  
B. Binary Computational Unit2 for Erosion:  
Erosion is fundamental operator of mathematical morphology, a theory for the analysis of spatial structure. The methods of mathematical morphology make possible a large number of very powerful image analysis techniques and therefore these operators and their implementations are of great theoretical and practical interest to many involved in image processing and analysis. The principle of Erosion operation is that the value of the output pixel is the minimum value of all the pixels in the input pixels neighbourhood.  
Erosion shrinks the connected sets of 1s in binary image. It can be used for Shrinking the shapes and Removing the bridges, branches and small protrusions.  
C .Binary Computational Unit3 for Dilation:  
Dilation expands the connected sets of 1s of the binary image. It can be used for Expanding the shapes and Filling the holes, gaps and gulfs. The principle of Dilation operation is the value of the output pixel is the maximum value of all the pixels in the input pixels neighbourhood.  
From the input image, (3x3) window is selected which contains 9 input pixels are sent to registers as shown in Figure5 & 6 and this is compared in min/max comparator. The max value gives the dilation result and min value gives erosion result. Comparison is done for remaining input pixels in the same manner. Here we are not using structuring element which has to be convolved with input image and then its compared, by doing without using structuring element we can reduce the hardware resources.  
D. Binary Computational unit4:Binarization  
Thresholding is a method to convert a Gray Scale Image into a Binary Image, so that objects of interest are separated from the background. For Binarization Fixed global thresholding method is used as shown in figure 7.Binarization or thresholding is the process that converts an image into blackandwhite: a threshold value is defined and the colours above that value are converted into white, while the colours below it are converted into black. This is a very simple process in digital image processing when one has a document with black ink written on a white paper. Document image binarization is an important step in the document image analysis and recognition pipeline. The performance of a binarization technique directly affects the recognition analysis.In order to reduce storage requirements and to increase processing speed, it is often desirable to represent gray scale as binary images by picking a threshold value. Binarization algorithms are classified into global and local methods. The global algorithms calculate one threshold for the entire image. The pixels are separated into two classes, foreground and background. By selecting an adequate threshold value T, the gray level image can be converted to binary image. The binary image should contain all of the essential information about the position and shape of the objects of interest (foreground). This can be expressed as in the equation
